> When a user topic which has been consumed in a share group is deleted, it is necessary to clean up the associated records on the share-group state topic. This could be driven from the GC or from the SC itself. Right now, the records remain forever, as do the ShareGroupStatePartitionMetadata entries for deleted topics. The SharePartitionManager does respond to topic deletion by observing metadata changes.
